Key Features and Advantages
The **MAE99-04** power module delivers industrial-grade reliability with its wide input voltage range and military-grade component selection. Its active power factor correction (PFC >0.98) ensures compliance with global energy standards while reducing harmonic distortion. The triple-stage protection system automatically recovers from faults without manual intervention, making it ideal for unmanned installations.
Optimized thermal design allows continuous operation at full load up to 70°C ambient temperature. The module’s reinforced insulation (4kV AC/1min) and surge immunity (6kV) provide exceptional resilience in electrically noisy environments. DIN-rail mounting compatibility and front-facing status LEDs enable rapid deployment and diagnostics in control cabinets.
